Perhaps a more diplomatic to phrase what I perceive as your thought there is that a good doctor or policeman is actually in some respects often acting that way regardless of the system -- they would've tried to help people as much as they could anyway. Meanwhile a bad or apathetic doctor, policeman, etc. will tend to receive little friction for it while you have to fight uphill to get basic care, all while being milked of as much of your money as possible and still having to wait unbearably long for useful treatment.

Likewise, there's such a range of outcomes, and when it's involving chronic diseases combined with an apathetic or bad doctor, you can be stuck realizing you've wasted months with no resolution (not even getting into any potential costs) only to now have to start all over again potentially several more times just for a sliver of hope that you'll find a doctor who's caring and competent enough to finally help you out. So sitting on the receiving end feels like being bled dry by people who couldn't care less about your suffering or if you die, so long as you keep paying them, with little realistic recourse other than accepting that you got burned and moving on.

In any case, just my two cents from what I think seems like a somewhat related view but with a different "spin".
